Missing part of URL

[MageGaHell]

I've installed this module on one of my site, using using :
composer require thelia/canonical-url-module:~1.1.0
No problem. But when i activate the module i've a error page (on each page):

The following error message has been found: The value "://staging.rikikilondon.com/Poppy-Dress.html" is not a valid Url or Uri.

Obviously, the https in the URL is missing.
